GEORGE F. CONNER, OF PORT I-IURON, MICHIGAN.

SPARK ARRESTER AND EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 663,148, dated December 4, 1900.

Application filed March 1,1900. Serial No. 6,971. (No model.)

T0 all whom, t may concern.-

Be it known that I, GEORGE F. CONNER, a citizen of the United States, residing at Port Huron, in the county of St. Clair and State of Michigan, have invented certain new and useful Improvements in Spark Arresters and Extinguishers, of which the following is a speciication.

This invention relates to an improvement in spark arresters and extinguishers; and it consists in the peculiar construction and arrangement of parts hereinafter described,'and denitely pointed out in the claim.

The invention relates particularly to that class of spark-arresters which have a conical sieve or reticulated depression at the center, with means for conducting the sparks back down to the stack; and the present invention is to provide a very simple, efiicient, and durable construction of the type above described which will contain a relatively7 few number of diiferent parts.

In the drawing I have shown the construction in longitudinal vertical section, parts being shown in elevation.

In the drawing, Arepresents a smoke-stack having securely riveted to its upper edge an outwardly-flaring casting d, the same being inclined upwardly and formed at its upper edge with a circumferential angular seat a', while the lower portion directly above the connection with the pipe A is formed with the horizontal seat a2, having a substantially vertical side wall d3. On the seat a. is se.- cured a tapering cylinder or casing B, the

l same being riveted to the edge of the casting d and extending upwardly to the top of the stack. On the upper end of this cylinder B is secured a circular cap or ringO of conical formation in cross-section, the outer edges being ared outwardly horizontally and resting on the corresponding edges on the top of the cylinder B. To secure the cap in place, pivoted clips or hooks O are secured to the cylinder, having their upper ends sprung over and engaging the upper surfaces of the anges of the ring. At this point suitable raised projections c are formed on the flange, over which the ends of the clips engage, so as to form secure connections.

Rising from the joint between the pipe A and casting a and having its lower edge secured in the seat d2 is a vertical partition E, slightly inclined outwardly and of circular formation. This partition extends upwardly to a point adjacent to the ring C, but slightly below the same, leaving a passage-way between. In the lower portion of the partition are formed a series of openings D'. The partition is securely fastened in place by rivets passing through the vertical walls a3 of the casting in the lower edge of the partition.

Secured to the inner periphery of the ring C is a depending conical-shaped deiiector F, made of wire conveniently and strengthened by vertical metallic stays j, to which it is secured, which latter are secured by suitable rivets to the ring. This deflector has on its lower end an imperforate pointed extension F', constituting the apex of the cone and to which the lower ends of the stays are ixedly secured.

In operation the imperforate point of the deliector is in line with the axis of the pipe A, and as the sparks are forced upward by `the draft the same engage or strike against the inclined walls of the deflector and are carried upward onto the inclined faces of the ring C outward and fall down in the space between the partition and cylinder B. They are then projected through openings at the base of the partition and fall downward through the pipe a at the sides. They are finally broken by repeated circulation or by impingement against the inclined surfaces of the arrester or dropped down to the bottom of the stack, where they are collected in any suitable receptacle.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a spark-arrester, the combination with a stack, of a casting secured to the upper edge thereof, a tapered cylindrical casing supported from the upper edge of the casting, an outwardly-extending flange on the upper edge of the casing, an inverted-Vshaped annular ring, a flange on one edge of the V adapted to rest on the corresponding flange of the casing, a deector secured to the opposite edge of the V so as to be detachable therewith, means for temporarily retaining the ring on the casing comprising clips exterior of the casing arranged to overlie the iiange of the IOO ring, and' at partition provided with openings at its lower end secured to the casting and extending upwardly between and unattaohed to the deiieotoi1 and Casing to a point diveetly beneath and in the hollow of the l2mn uler ring, substantially as and for the purpose described.

In testimony whereof I aix my signatnl'e in presence of two witnesses.

GEORGE F. OONNER.
